I´m with everybody else. Slice is a problem, topspin not. If Mona has a normal day she should win. She can talk herself into the underdog role (she seems to enjoy) against a top 10 player, even when she should be favoured based on the surface and match-up. Players with a big serve and return are basically the death sentence for Errani´s game. But if Errani can get into the rallies Barthel will be in a world of hurt.
